Using:
Laravel 8
PHP 8.0 (homebrew)
Problem:
Running any shell commands using Symfony: Symfony\Component\Process\Process
The following code executes on php7.4, but not on php8.0, both within Laravel 8
$newDir = storage_path('test');
$process1 = new Process(["mkdir ". $newDir]);
$process1->run();
if (! $process1->isSuccessful()) {
throw new ProcessFailedException($process1);
}
The result on PHP 7.4 is that the test directory is created within Laravels storage directory.
The result on PHP 8.0 is that the exception ProcessFailedException is triggered, with the result.
Error Output:
================
sh: /Users/username/code/project-name/mkdir /Users/username/code/project-name/storage/test: No such file or directory
sh: line 0: exec: /Users/username/code/project-name/mkdir /Users/username/code/project-name/storage/test: cannot execute: No such file or directory
I have attempted to use other commands and all give the same result
cannot execute: No such file or directory
My suspicion is that it may be permissions related, but all related processes can be seen running as the user executing the process. What am i missing?
Use a full path i.e. /bin/mkdir and separate the arguments instead of mkdir plus string concatenation.
$process1 = new Process(["/bin/mkdir", "-p", $newDir]);
The Process component can't find an executable with name mkdir [arguments] in your current working directory.

I have a C program that I wrote called convert3to5, originally written for CentOS / Fedora 32bit system in early 2010. I am moving it to new CentOS 6.x 64bit system host.
From a CentOS Putty console I can run the convert3to5 command just fine; here is a sample of it running from my console:
[root#cloud convert3to5]# ls
CircleStar convert3to5 Convert3To5.txt test.tif
[root#cloud convert3to5]# ./convert3to5 /var/www/webadmin/data/www/mydomain.com/uploads/SV-DIS160217B.tif
TIFFReadDirectory: Warning, /var/www/webadmin/data/www/mydomain.com/uploads/SV-DIS160217B.tif: wrong data type 7 for "RichTIFFIPTC"; tag ignored. Image has an undefined fillorder - using default: MSB2LSB
The above is a normal completion of convert3to5 and I get a SV-DIS160217B.bmp that is placed in /var/www/webadmin/data/www/mydomain.com/uploads/ So running it from console works fine.
Question - I am attempting to run the same exact command from PHP using the exec(command, output, return) command as follows:
chdir($sv_path.$c3to5_path); //change our working directory to "/convert3to5" directory
$command = "./convert3to5 $targetFile 2>&1";
$result = exec($command, $output, $return);
// the output of the above command - is a .bmp file it will be placed in the same path as the input .tif file
I get the following $result:
ERROR: Unable to convert
/var/www/webadmin/data/www/mydomain.com/uploads/SV-DIS160217B.tif to 5
color BMP file: Open file Error: Tiff_3_to_BMP_5_.lut!
My convert3to5 does need to open Tiff_3_to_BMP_5_.lut
Why does it find Tiff_3_to_BMP_5_.lut when I run convert3to5 from a console prompt but not from PHP exec(...) in both cases my pwd shows that I am in
[root#cloud convert3to5]# pwd
/var/www/webadmin/data/www/mydomain.com/myView/convert3to5
I have also verified pwd is correct from my PHP script after the
chdir($sv_path.$c3to5_path);
Tiff_3_to_BMP_5_.lut is in CircleStar directory - the path to CircleStar is /var/www/webadmin/data/www/mydomain.com/myView/convert3to5/CircleStar
Summary: ./convert3to5 works while PHP exec('convert3to5 ..) does not appear to work.
Can anyone suggest the difference and how to fix and/or debug?
Thanks
You're running the console from the convert3to5 directory, and I suspect your old C program used a relative path to the .lut file, possible relative to the .tif?
What if in the console example you did
cd ../..
./path/to/convert3to5/convert3to5 /var/www/webadmin/data/www/mydomain.com/uploads/SV-DIS160217B.tif
Might be related to $targetFile. Print that and see if it's the full path.
Finally, run
/full/path/to/convert3to5 fullTargetPath
If that works, then as a workaround, if you just do exec('/full/path/to/convert3to5 $fullTargetPath, ..) it should behave like the console.
Per my above comment to wonton:
From the console I was running as root (so fully privileged). I supposed my PHP script will run as the "apache" user on the server?
Here was the problem I believe: I looked at the CircleStar directory privileges where the Tiff_3_to_BMP_5_.lut file exists. CircleStar had rw-r--r-- (0644) when running as root from console this allowed my convert3to5 program to find and open Tiff_3_to_BMP_5_.lut file just fine. However not the PHP exec(...) once I changed the privilege on CircleStar to rwxr-xr-x (0755) PHP exec(...) ran fine!
So ultimately it was a permission issue.
I have setup OpenCV 3.0 with python3.4 binding on ubuntu 14.04. I run OpenCV using virtualenv. So, everytime I have to run the workon cv command.
Now I want to run a python script that uses OpenCV library from PHP using the exec command.
exec("workon cv");
exec("python3 hough_circles.py")
This is the error :
sh: 1: workon: not found
Traceback (most recent call last):
File "hough_circles.py", line 1, in <module>
import cv2
ImportError: No module named 'cv2'
Two issues...
1. PATH to workon
The error message is telling you it doesn't know where workon is, so you better tell it the full path to where it is so exec() can find it, e.g.:
exec("/usr/local/bin/workon cv");
The /usr/local/bin above is just an example, if you want to know where it is on your system, run:
which workon
and use the output.
2. Subprocesses are independent
Even when you have got that set correctly, the process that executes workon then exits and you start a fresh, shiny new one - in which you have not run workon. So, you better do both things in the same process like this:
exec("/usr/local/bin/workon cv && /path/to/python3 hough_circles.py");
I have the following PHP code that is run when a user clicks a button on a local intranet page to run some Node JS commands. e.g.
exec('npm install', $output);
$output = implode(PHP_EOL, $output);
echo $output;
But the command doesn't seem to get run... It does if I type the command into the command prompt and run it...
I don't see any errors and NodeJS is set as a system variable in the Path so it should know what grunt is... Any ideas? Other commands, e.g. whoami run fine.
Any ideas?
I'm on Windows 7.
Update: Based on the comments below I can now get an error with:
exec('npm install 2>&1', $output, $returnCode);
$output = implode(PHP_EOL, $output);
echo $output . ' ' . $returnCode;
And this is the error:
TypeError: Cannot call method 'get' of undefined at C:\Program Files (x86)\nodejs\node_modules\npm\lib\npm.js:310:23 at C:\Program Files (x86)\nodejs\node_modules\npm\node_modules\npmconf\npmconf.js:80:7 at Array.forEach (native) at C:\Program Files (x86)\nodejs\node_modules\npm\node_modules\npmconf\npmconf.js:79:13 at f (C:\Program Files (x86)\nodejs\node_modules\npm\node_modules\once\once.js:16:25) at C:\Program Files (x86)\nodejs\node_modules\npm\node_modules\npmconf\npmconf.js:108:14 at Conf.

So it looks like the PHP knows where NodeJS and NPM is... but can't run it?
If I do whoami in the PHP I get: nt authority\iusr
But if I do it from the command prompt then I get: dom\cameron
I wonder if it's because PHP runs it as a different user to when I run it directly in the command prompt...
Okay I've managed to fix this!
Basically you need to run the website (where the PHP file lives) as the same user as where NodeJS is run from!
To achieve this I did the following in IIS:
1.) Find the website
2.) Choose basic settings
3.) Click the connect as... button
4.) Choose 'specific user'
5.) Enter `dom/cameron` and my password
6.) Restart IIS
If anyone has any ideas for how to get NodeJS running for the default nt authority\iusr then feel free to post an answer :)
You defined npm in WINDOWS path, but did PHP recognize it?
I suggest you should test it with writing the full NPM path in the exec. If it works, than you should call putenv() with correct parameters before executing npm install..
So first try:
exec('C:\npm-test\npm install', $output);
$output = implode(PHP_EOL, $output);
echo $output;
And if it works, use the putenv() command before calling exec(). Example:
putenv("npm='C:\npm-test\npm'");
//and then exec(...)
The error you're getting indicating that an object is not defined. It's quite possible that a module is simply not loading because you're not running the script from the correct location, and relative links to some include are not working. Running as the correct user might fix it. Or try changing to the correct directory before running the node script. Or change the location of the links inside the node script.
I am trying to convert .docx file to .html using php shell_exec in CentOS 6.5
My php code:
$command = "libreoffice --headless -convert-to html resume.docx 2>&1";
$result = shell_exec($command);
echo $result;
When I run the index.php at http://localhost/converter/ it gives me:
javaldx: Could not find a Java Runtime Environment! Warning: failed to read path from javaldx /usr/lib64/libreoffice/program/soffice.bin X11 error: Can't open display: Set DISPLAY environment variable, use -display option or check permissions of your X-Server (See "man X" resp. "man xhost" for details)`
while in terminal it is working perfectly:
cd /var/www/html/converter/
libreoffice --healdess -convert-to html resume.docx
here it creates resume.html in my /var/www/html/converter/.
Hi i have the same problem, i want to convert PDF's from DOCS created with PHP, i'm using OpenSuse 12.3 with LibreOffice, tried many things, finally i detect that the error is in folder:
1.- First check that you don't have disabled shell_exec in php.ini, and open_basedir don't restrict your access folders.
2.- Run the command as a simple user in shell (terminal)
export HOME=/tmp && soffice --headless --convert-to pdf --outdir /srv/www/htdocs/ /srv/www/htdocs/Creecimientos/sic/app/webroot/usuarios/2/8_Pagare_CreePersonas.docx
3.- If it works, you only have to put the correct folders in your code, when i run this code in PHP, it show me a blank page, so i check the access_log of apache for any hint:
[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed!
Warning: failed to read path from javaldx
terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'
Note: my error was in using export HOME=/tmp, i checked that the folder in root system has 777 for tmp, but the problem was that apache don't acces to it, maybe search for a relative folder of the script, but after test many things i only put a folder with permissons for wwwrun HOME=/srv/www/htdocs/folder_with_777
This is my final code, that works..
<?php
function word2pdf()
{
echo "Procesando";
$result = shell_exec('export HOME=/srv/www/htdocs/Creecimientos/sic/ && soffice --headless --convert-to pdf --outdir /srv/www/htdocs/Creecimientos/sic/ /srv/www/htdocs/Creecimientos/sic/app/webroot/usuarios/2/8_Pagare_CreePersonas.docx');
echo $result;
}
word2pdf();
?>
In fact, it prints: convert srv/www/htdocs/Creecimientos/sic/app/webroot/usuarios/2/8_Pagare_CreePersonas.docx -> /srv/www/htdocs/Creecimientos/sic//8_Pagare_CreePersonas.pdf using writer_pdf_Export, after succes.
I made other changes before in desesperate mode, but none of them solved the problem, tried to change owner to soffice wich found it witch $ ls -l $(which libreoffice), tried with 777, etc..
/* This command will work on centos 6 /7 with installation of libreoffice headless package */
First install package on centos as :
yum install libreoffice-headless
/* following code work to extract text format from */
<?php
$result = exec("export HOME=/tmp/ && /usr/bin/libreoffice --headless --convert-to txt:Text --outdir /tmp filePath");
var_dump($result);
?>
Most likely the user that LibreOffice is ran as, does not have a writeable home directory so LibreOffice fails to create it's config directory and then it cannot create it's config files and then fails to load Java, because it cannot write the default config. A bit silly I know.
Try adding this parameter: -env:UserInstallation=file:///tmp/whateverhere
I don't have enough reputation to comment on TD_Nijboer's answer, but the answer to his specific problem appears to be that soffice needs to be able to read & write config information somewhere. The first place it tries to do this is the libreoffice directory in ~/.config ('~' means "the current user's home directory").
In Debian, by default, the www-data user has the home directory /var/www, and does not have write permission there.
If you make sure it has permission to either create ~/.config itself, or libreoffice within an existing ~/.config, I expect it will work.
2 things, 1st the command is soffice --headless,
2nd i have an similar javaldx error and it has to do with permission.
when executing as root it works fine, but php executes as www-data.
if anybody knows a good way to execute libreoffice from php please let me know.
as i'm getting an error code 77 saying:
[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed!
Warning: failed to read path from javaldx
I'm using Unison to sync files between two servers. I'm trying to get PHP to call it after a file is uploaded.
I'm using exec, but it's returning an error code of 2.
exec("/usr/bin/unison /var/www/html/files ssh://a2//var/www/html/files -batch -prefer newer -times -path uploads", $out, $r);
$out is a blank array, and $r is 2. What does an error code of 2 mean?
P.S. I ran php -a on the command line, and copied and pasted that line, and it worked. Also, exec('whoami') works (and is the same user I was logged in as on the command line).
I fixed it! Using popen (thanks #sberry2A) I saw an error.
Fatal error: Error in creating unison directory /.unison: Permission denied [mkdir(/.unison)]
I ran chdir('/home/user');, before running the command, and then saw an error about HOME not being set.
So, I added HOME=/home/user before the command. Now it works, and I don't need the chdir command either!
exec("HOME=/home/user /usr/bin/unison /var/www/html/files ssh://a2//var/www/html/files -batch -prefer newer -times -path uploads", $out, $r);
